SpriteSheetFn

By default the picker source the emoji sheets online, this may not be the best solution and you may want to bundle the emoji sheets with your app. For the best results it's recommended to include any emoji sheets you use in the platform specific app package.

You can either provide your own emoji sheets or use ones available from libraries such as iamcal/emoji-data:

npm install emoji-datasource-apple
npm install emoji-datasource-google
npm install emoji-datasource-twitter
npm install emoji-datasource-facebook
import { Picker } from 'rn-emoji'

const localSpriteSheets = {
  ...
  twitter: {
    ...
    '20': {uri: `https://unpkg.com/emoji-datasource@5.0.1/sheet_${set}_${sheetSize}.png`}, // Loads asset from web
    '32': require('./node_modules/emoji-datasource-twitter/img/twitter/sheets/32.png'), // Loads static asset
    '64': {uri: 'twitter_emoji_64'}, // Loads asset from app package
  },
  ...
};

<Picker spriteSheetFn={(set, sheetSize) =>
  {uri: `https://unpkg.com/emoji-datasource@5.0.1/sheet_${set}_${sheetSize}.png`}
}>
<Picker spriteSheetFn={(set, sheetSize) =>
  localSpriteSheets[set][sheetSize]
}>

Sheet sizes

Sheets are served from unpkg, a global CDN that serves files published to npm.

Set Size (sheetSize: 16) Size (sheetSize: 20) Size (sheetSize: 32) Size (sheetSize: 64)
apple 407 KB 561 KB 1.34 MB 3.60 MB
facebook 416 KB 579 KB 1.38 MB 3.68 MB
google 362 KB 489 KB 1.12 MB 2.78 MB
twitter 361 KB 485 KB 1.05 MB 2.39 MB

Datasets

While all sets are available by default, you may want to include only a single set data to reduce the size of your bundle.

Set Size (on disk)
all 611 KB
apple 548 KB
facebook 468 KB
google 518 KB
twitter 517 KB

To use these data files (or any other custom data), use the NimblePicker component:

import data from 'rn-emoji/data/apple.json'
import { NimblePicker } from 'rn-emoji'

<NimblePicker set="apple" data={data} />

Examples of emoji object:

{
  id: 'smiley',
  name: 'Smiling Face with Open Mouth',
  colons: ':smiley:',
  text: ':)',
  emoticons: [
    '=)',
    '=-)'
  ],
  skin: null,
  native: '😃'
}

{
  id: 'santa',
  name: 'Father Christmas',
  colons: ':santa::skin-tone-3:',
  text: '',
  emoticons: [],
  skin: 3,
  native: '🎅🏼'
}

{
  id: 'octocat',
  name: 'Octocat',
  colons: ':octocat:',
  text: '',
  emoticons: [],
  custom: true,
  image: {uri: 'https://github.githubassets.com/images/icons/emoji/octocat.png'}
}

Local image requires

By default the picker source the emoji images online, this may not be the best solution and you may want to bundle the emojis with your app.

Set Size (on disk)
all 1.6 MB
apple 776 KB
facebook 690 KB
google 742 KB
twitter 752 KB

To use local image requires you need to install the individual sets you need in your project using the individual sets npm packages from https://github.com/iamcal/emoji-data#installation:

npm install emoji-datasource-apple
npm install emoji-datasource-google
npm install emoji-datasource-twitter
npm install emoji-datasource-facebook
import { NimblePicker, NimbleEmoji } from 'rn-emoji'
import data from 'rn-emoji/data/facebook.json'
import dataRequires from 'rn-emoji/data/local-images/facebook'
const {emojis: localEmojis} = dataRequires

useLocalImages false Local image requires
skin 1 Skin color: 1, 2, 3, 4, 5, 6

Unsupported emojis fallback

Certain sets don’t support all emojis. By default the Emoji component will not render anything so that the emojis’ don’t take space in the picker when not available. When using the standalone Emoji component, you can however render anything you want by providing the fallback props.

To have the component render :shrug: you would need to:

<Emoji
  set={'apple'}
  emoji={'shrug'}
  size={24}
  fallback={(emoji, props) => {
    return emoji ? `:${emoji.short_names[0]}:` : props.emoji
  }}
/>

Custom emojis

You can provide custom emojis which will show up in their own category. You can either use a single image as image or use a spritesheet as shown in the third object.

import { Picker, NimbleEmoji, getEmojiDataFromCustom } from 'rn-emoji'

const customEmojis = [
  {
    name: 'Octocat',
    short_names: ['octocat'],
    text: '',
    emoticons: [],
    keywords: ['github'],
    image: {uri: 'https://github.githubassets.com/images/icons/emoji/octocat.png'},
    customCategory: 'GitHub'
  },
  {
    name: 'Trollface',
    short_names: ['troll', 'trollface'],
    text: '',
    emoticons: [],
    keywords: ['troll'],
    image: require('assets/trollface.png')
  },
  {
    name: 'Test Flag',
    short_names: ['test'],
    text: '',
    emoticons: [],
    keywords: ['test', 'flag'],
    spriteSheet: {uri: 'https://unpkg.com/emoji-datasource-twitter@5.0.1/img/twitter/sheets-256/64.png'},
    sheet_x: 1,
    sheet_y: 1,
    size: 64,
    sheetColumns: 60,
    sheetRows: 60
  },
  {
    name: 'Test Flag',
    short_names: ['test'],
    text: '',
    emoticons: [],
    keywords: ['test', 'flag'],
    spriteSheet: require('assets/twitter/sheets-256/64.png'),
    sheet_x: 1,
    sheet_y: 1,
    size: 64,
    sheetColumns: 60,
    sheetRows: 60
  }
]

<Picker custom={customEmojis} />

const emoji = getEmojiDataFromCustom('troll', customEmojis, emojiData);

<NimbleEmoji
  data={emojiData}
  custom={customEmojis}
  skin={emoji.skin || null}
  set={emojiSet}
  emoji={emoji}
  size={16}
/>

The customCategory string is optional. If you include it, then the custom emoji will be shown in whatever categories you define. If you don't include it, then there will just be one category called "Custom".

Not Found

You can provide a custom Not Found object which will allow the appearance of the not found search results to change. In this case, we change the default 'sleuth_or_spy' emoji to Octocat when our search finds no results.

import { Picker } from 'emoji-mart'

const notFound = () => <Image style={{width: 48, height: 48}} source={{ uri: "https://github.githubassets.com/images/icons/emoji/octocat.png" }} />

<Picker notFound={notFound} />

Custom category emojis

You can provide custom emojis for the category anchors. You only need to supply the ones you want changed from the default ones.

import { Picker } from 'emoji-mart'

const categoryEmojis = {
  recent: 'fire',
  people: 'see_no_evil',
  nature: 'beetle',
  foods: 'kiwifruit',
  activity: 'table_tennis_paddle_and_ball',
  places: 'airplane',
  objects: 'postal_horn',
  symbols: 'copyright',
  flags: 'triangular_flag_on_post',
  custom: 'hammer_and_wrench',
}

<Picker categoryEmojis={categoryEmojis} />

Headless search

The Picker doesn’t have to be mounted for you to take advantage of the advanced search results.

import { emojiIndex } from 'rn-emoji'

emojiIndex.search('christmas').map((o) => o.native)
// => [🎄, 🎅🏼, 🔔, 🎁, ⛄️, ❄️]

With custom data

import data from 'rn-emoji/datasets/facebook'
import { NimbleEmojiIndex } from 'rn-emoji'

let emojiIndex = new NimbleEmojiIndex(data)
emojiIndex.search('christmas')

Get emoji data from Native

You can get emoji data from native emoji unicode using the getEmojiDataFromNative util function.

import { getEmojiDataFromNative, Emoji } from 'rn-emoji'
import data from 'rn-emoji/data/all.json'

const emojiData = getEmojiDataFromNative('🏊🏽‍♀️', 'apple', data)

<Emoji
  emoji={emojiData}
  set={'apple'}
  skin={emojiData.skin || 1}
  size={48}
/>

Example of emojiData object:

emojiData: {
  "id": "woman-swimming",
  "name": "Woman Swimming",
  "colons": ":woman-swimming::skin-tone-4:",
  "emoticons": [],
  "unified": "1f3ca-1f3fd-200d-2640-fe0f",
  "skin": 4,
  "native": "🏊🏽‍♀️"
}

Storage

By default EmojiMartNative will store user chosen skin and frequently used emojis in localStorage. That can however be overwritten should you want to store these in your own storage.

import { store } from 'rn-emoji'

store.setHandlers({
  getter: (key) => {
    // Get from your own storage (sync)
  },

  setter: (key, value) => {
    // Persist in your own storage (can be async)
  },
})

Possible keys are:

Key Value Description
skin 1, 2, 3, 4, 5, 6
frequently { 'astonished': 11, '+1': 22 } An object where the key is the emoji name and the value is the usage count
last 'astonished' (Optional) Used by frequently to be sure the latest clicked emoji will always appear in the “Recent” category

Features

Not opinionated

Emoji Mart Native doesn’t automatically insert anything into a text input, nor does it show or hide itself. It simply returns an emoji object. It’s up to the developer to mount/unmount (it’s fast!) and position the picker. You can use the returned object as props for the EmojiMartNative.Emoji component. You could also use emoji.colons to insert text into a textarea or emoji.native to use the emoji.

Removing prop-types

To remove prop-types in production, use babel-plugin-transform-react-remove-prop-types:

npm install --save-dev babel-plugin-transform-react-remove-prop-types

Then add to your .babelrc:

"plugins": [
  [
    "transform-react-remove-prop-types",
    {
      "removeImport": true,
      "additionalLibraries": [
        "../../utils/shared-props"
      ]
    }
  ]
]

You'll also need to ensure that Babel is transpiling rn-emoji, e.g. by not excluding node_modules in babel-loader.

Development

yarn build

Testing Changes

To easier test changes as you make them, you can run yarn build:link -- --out-dir /$project/node_modules/rn-emoji/dist replacing $project with your projects or the example apps location.
